Abstract

The invention discloses a rotor iron core for a brushless electric machine and belongs to the field of fans.The rotor iron core solves the problem that in the prior art, the magnetic flux leakage phenomenon of a rotor of an electric machine is serious.The rotor iron core for the brushless electric machine comprises a rotor body, the rotor body comprises a magnetism insulating bracket provided with a shaft hole, the periphery of the magnetism insulating bracket is provided with a plurality of iron cores at intervals, and a mounting groove for mounting a corresponding magnet is formed between every two adjacent iron cores.

Description

【Technical field】 [0001] The invention relates to a rotor of an electric machine. 【Background technique】 [0002] In recent years, permanent magnet synchronous generators have been used more and more because of their advantages such as high efficiency, good low-speed power supply performance, low voltage adjustment rate, simple structure, reliable operation, and stable performance. There are two types of rotor laminations for permanent magnet generators: surface type and built-in type, among which the built-in rotor laminations are widely used. However, the magnetic flux leakage in the existing rotor is large, and the effective utilization rate of the permanent magnets is low, and the application to the fan will affect the heat dissipation and working performance of the fan. 【Content of invention】 [0003] The technical problem solved by the invention is to provide a rotor iron core for a brushless motor to improve the performance of the rotor. [0004] In order to solve...
